Frequently Asked Questions

Is the C-90B effective
against mold?
The Friedrich C-90 works based on particle size, eliminating airborne
particles as small as .01 microns. Mold spores generally range in size
from 10 to 30 microns.

A word of
caution though - this applies to airborne particles only. Friedrich, and
any reputable manufacturer, does not make claims as to an air cleaner
helping to eliminate mold from walls and other large objects.
